The Komodo Dragon: The World's Largest Lizard Is Now Endangered

In brief

The Komodo dragon (Varanus komodoensis) is an Endangered monitor lizard endemic to a handful of Indonesian islands — Komodo, Rinca, Gili Motang, Padar and the western coast of Flores — with an estimated wild population of around 3,000-3,500 individuals.

Key Takeaways

  • World's largest living lizard species — adults can exceed 3 metres and 70 kg.
  • Listed as Endangered on the IUCN Red List in 2021 (uplisted from Vulnerable).
  • Endemic to a handful of small Indonesian islands inside Komodo National Park and western Flores.
  • Wild population estimated at 3,000-3,500 individuals.
  • Primary threat is climate change — predicted sea-level rise would inundate critical low-lying habitat.

The Komodo dragon (Varanus komodoensis) is the largest living lizard. It is also one of the most range-restricted apex predators on earth — endemic to a handful of Indonesian islands totalling less than 1,800 km² of suitable habitat. In 2021 the IUCN moved it from Vulnerable to Endangered.

The Komodo dragon lives entirely within Indonesia, which is one of WARN's ten operating countries. We do not currently fund Komodo work, but the same Indonesian Ministry of Environment and Forestry, the same conservation NGOs, and the same partner veterinary capacity that any Komodo conservation work depends on are the institutions our Indonesia programme is being designed to interact with.

Why the Komodo dragon is Endangered

  • Climate change and sea-level rise. The IUCN's 2021 reassessment cited modelled sea-level rise as a critical threat — much of the dragon's prime habitat is low-lying coastal valley.
  • Prey depletion. Komodo dragons depend on Timor deer, wild boar and water buffalo. Poaching of deer for bushmeat reduces the dragon's food base.
  • Range fragmentation. The Flores population is fragmented into small subpopulations, several of which are now genetically isolated.
  • Tourism pressure. Komodo National Park is one of Indonesia's most-visited protected areas. Sustainable tourism funds the park, but uncontrolled access stresses dragons and disrupts mating behaviour.

What conservation looks like

Komodo National Park and Wae Wuul Nature Reserve are the backbone of Komodo dragon conservation, with day-to-day work led by Indonesian forestry-ministry staff. CITES Appendix I prohibits commercial international trade. Captive-breeding insurance populations exist in a small number of zoos worldwide.

How WARN fits in

The Komodo dragon is not a WARN appeal and is unlikely to become one — long-term species conservation of a single endemic apex predator is the field of established Indonesian and international conservation organisations. We have included this briefing because the Komodo dragon is one of the most-searched Indonesian endangered species online, and we want WARN supporters who search for it to find an accurate, source-cited summary rather than the fundraising-driven copy that dominates other charity websites.
